<div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">I haven't dug too deep, but one strange thing I think I saw on a spec sheet was that the "micro-AC Grid" (aka microinverter) is UL 1703. If that is the case, how does the PV continue to provide water heating in a utility outage? What I really don't understand is why there is a need for a microinverter at all? Why not just use a DC element? I guess a microinverter, despite minor efficiency losses, is cheaper than a load controller.</div>
